TOOTH PASTE DISPENSING DEVICE Filed Aug. 3o, 192'? Patented Jan.- 7, 1930 UNITED STA maar museum, or cmusmns ein, Iowa 'OOTHPABTE-DISPENSIN G DEVICE I Application led August 30,

This invention relates to improvements in tooth paste dispensing devices.

The object ot' my invention is to provide a dispensing device of simple, durable, and inexpensive construction, constructed to support a collapsible tube of tooth paste in such a manner that measured quantities of the tooth paste may be dispensed, and provided with means for automatically closing the discharge opening of the dispenser when the device is not in use.

My invention consists in the construction, arrangement and combination of the various parts of the device, whereby the objects contemplated are attained, as hereinafter more fully set forth, ointed out in my claims, and illustrated in t e accompanying drawings,

in which:

Figure 1 is a side elevation of my improved 2o dispenser with a tube of tooth paste mounted therein.

Figure 2 is a longitudinal sectional view of same.

Figure 3 is a detail sectional view taken on the line 3-3 of Figure 2.

Figure 4 is a detail sectional viewv taken on the line 4 4 of Figure 2.

Figure 5 is a detail sectional view taken on the line 5-5 of Figure 2.

Figure 6 is a detail side elevation of the front end of the dispenser, illustrating in detail the locking mechanism.

My improved device comprisesa body portion 10 having the form of a flat plateof a length slightly greater than the length of the tube 11, and of awidth equal to the width of the flattened end 12 of said tube. The front end of the member 10 is provided with a head 13 having a screw threaded opening 14 for receiving the screw threaded end 15 of the tube 11. The head 13 is provided with a discharge nozzle l5 having a'discharge opening 16. The plate ,10 is slightly inclined with the center line'of the screw threaded member 15a of the tube 1l su ported in the opening 14. The flattened en 12 of said tube may be rotated without engaging the member `10. The tube assumes the dotted line osition shown in Figure 2 when it is being p aced in 50 position. The tube is rotated until the mem- 1927. Serial" No. 216,427.

ber 12 is parallel with the back end of the plate 10, after'which it is bent downwardly until the tube rests on the plate l0, inthe manner illustratedin Figure 1, with the flattened member'12 against the body portion l0. 55

The head 13 is provided with an upwardly eistending member 17 which terminates yin a hinge portion 18 to which is pivotally connected a head member 19 having a semi-cylindrical frame member 2O supported substano0 tially parallel with the member 10, and a forwardly extending portion 21 supported above the nozzle 15. The free end of the member 21 1s provided with a spring actuated gate 22 for closing and opening the opening 16 as the 65 member 2l is oscillated on its pivot member 23.

The back of the member 21 is provided with a bearing 24 in which is rotatively mounted a screw threaded shaft 25, the forward end of which is rotatively mounted in the head 19. The rear end of the shaft 25 is provided with a knurled knob 26.. The shaft 25 isA provided with a screw threaded sleeve 27 designed to it the interior of the ,75 member 20 and to travel longitudinally thereof. lSaid'sleeve 27 is provided with a downwardly extending arm 28 which terminates in a pressure foot 29 adapted to engage the free end of the tube 11 and to col- 80 lapse the tube as the free end of the member 20 is moved inwardly toward the member 10. The sleeve is advanced forwardly as the free end of the member 20 is elevated by means of a ratchet wheel 30 secured to the front of the g5 shaft 25and actuated by means of a pawl 31, the front end of which is pivotally connected to a pin 32 mounted in the back end of the head member 13, as illustrated in Figure 3.

By this arrangement it will be seen that if the free end of the member 20 is elevated, the pawl 31 will engage `the teeth of the ratchet 3() and cause the same to rotate the shaft 25 through a art revolution, and to advance the sleeve 2 ai slight distance de- 95 pending on the amount of rotation of the shaft 25 and the pitch of the threads thereon.

It will be seen that if the free end of the member 20 is moved toward the plate 10 by the operator placing one finger through 100 `a loop 33 and engaging the free end of the member 20 with his thumb and imparting a squeezing action to the members and 2G, it will cause the pressure foot 29 to be forced' 5 downwardly on the outer end of the tube 11,

0f the plVO In the normal operation of the device, the free end ofthe member is limited to travel through a comparatively small angle by means of a dog 36 supported on a pivot 37 90 mounted in the head 13 and designed to engage a pin 38 in the head 19. A suitable spring 39 is provided for retaining the dog in its latched position with the member 420 substantially -in the position illustrated inl Figure 1. When it is desired to place the tube in position, then the dog 36 is moved out of engagement with the pin 38, permitting the member 20 to move to the dotted line position shown in Figure 2, after which the tube ao may be easily inserted under the foot 29.

The pawl 31 is provided with an outwardly extending arm 40 which provides means whereby the said pawl may be caused to disengage the ratchet 30, after which the knob 26 may be actuated to return the foot 29 from' its forward position of movement to its rearward position of movement. This movement takes place before the dispenser is refilled.

Thus it will be seen that I have provided a dispenser particularly adapted to dispense measured quantities of tooth paste from a commercial type of collapsible tube in common use, and which may be easily operated, and positive in its action.

One advantage of my construction lies in the fact that the foot 29 is pressed against 1, the outer end of the tube 11 in such a manner that the member 20 is moved inwardly toward the member 10 by power derived from the. operators hand, the foot 29 being advanced forwardly as the member moves outwardly, and at a time when no pressure is heilig applied to the foot or the operating mechanism, thereby providing means whereby the operating devices are relieved of all unnecessary strain, and providing means whereby said operating devices may be of comparatively light construction and free fromA unnecessary wear.

Another advantage of my construction lies in providing the spring actuated gate 22 for closing the delivery opening 16. rl"he gate is normally closed by means of a spring 41 which provides means whereby the said gate of the nozzle 15 for positively retaining the o ening 16 closed, regardless of the position or the gate thereon, and provides for any wear otally mounted to said body portion and movable toward and from a tube supported in said body portion, a pressure foot carried by said i'rame member and movably mounted ,relative to said "frame and in longitudinal relation with said tube, said pressure foot being adapted to engage the free end of the inner face of said tube and collapse the same as the frame member is moved inwardly, and

means 'operatively connected to said pivoted lrame and actuated by its outward movement for advancing said pressure foot toward the delivery end of said tube.
